Median Orbit Repeatability (see table below): 12.0 cm

We continue to exclude data from IGS stations that do not employ Dorne-Margolin
style antennae (see IGS Report #6260).

Analysis results from day 023 (week 1046) are not available at this time.
As such, statistics for day 022 in this week's Orbit Repeatability table below
are indicative of comparisons with the previous day (021) only.

Due to potential problems, data from stations mentioned below were not
considered for use in the global solution for the day indicated.  (For
geographical reasons, they may not have been used in any case.)

WARNING: ALGO (not USNO) used as reference clock days 016-018, 021, and 022.
WARNING: FAIR (not USNO) used as reference clock day 019.
WARNING: PIE1 (not USNO) used as reference clock day 020.
WARNING: Data from PRN11 and PRN15 excluded the entire GPS week 1045.
WARNING: Data from EISL, GOL2, GUAM, MEDI, PETP, SPK1, TID2, PRN07, PRN08                excluded day 016.
WARNING: Data from GOL2, KOKB, PETP, USNO, PRN08 excluded day 017.
WARNING: Data from DARW, GOL2, IISC, PETP, TID2, TORP, TSKB, VENE, PRN18,                PRN26 excluded day 018.
WARNING: Data from DARW, GODE, GOL2, IISC, KOKB, PETP, QUIN, TID2, TORP, YSSK,           PRN18 excluded day 019.
WARNING: Data from BRUS, DARW, EISL, GOL2, TID2, TORP, TSKB, USNO, WTZT, YSSK,           PRN18 excluded day 020.
